This video demonstrates the key steps in performing smartphone ophthalmoscopy using an iPhone 5. Many filming applications can be used; we prefer the Filmic Pro App (00:09), because its light intensity can be lowered, which is more comfortable for the subject and produces less glare. The subject’s pupil should be dilated with an appropriate mydriatic. If performing the technique as a “selfie,” it is advantageous to sit in front of a mirror (00:29), so that one can monitor the quality of the recorded video in the mirror reflection. To save a photograph of the fundus findings, a screenshot can later be taken of the recorded video’s findings (00:49).
